So how do I condition my fish for breeding? I haved heard several people say that they feed their bettas until they look likethey are going to burst, also I have heard that you don't always need to feed them live food. So what are your suggestions?

Basically they need high protein foods. Betta's love live foods, but you don't have to use them to condition. Instead you could use frozen foods like f. blood worms, daphnia or what ever is available in your area. Just cut off a small piece at a time and .... defrost (?) (sorry can't think of the right word) before feeding. Don't defrost the whole cube - keep it as fresh as possible.
I'm not sure of man made foods though (I've never used them)

You don't have to feed them till their bellies are ready to pop. I feed until they begin to slightly bloat. Too much feeding is believed to cause more harm than good.

Freeze dried bloodworms have almost no nutrition! If all you feed your betta is the freeze dried stuff, they will eventually get sick from a lack of nutrition. Someone else posted their fish as being sick and all they fed were freeze dried bloodworms, I suggested pellets and their betta is doing much better!
You need to be using a pellet food for the main staple, but if you're conditioning, I would use live foods or frozen food.

If you have a Petsmart or Petco nearby, I would look there. They have a small refrigerator next to their tropical fish where they keep frozen food. Petsmart has frozen bloodworms for like $3.99 and you get 30 separate cubes for easy feeding.
